hey guys...I live in South Africa so we use 220V-240V AC. Im looking for ways to to interface the arduino with such power sources for things like home lighting. Basic on and off is fine but my biggest problem and focus is accomplishing a dimming function. what are my options as far as thats concerned?

i acknowledge the risk involved but i meant specifically the mosfet needed. applying it is no problem...in addition i found this just now online: although the site disclaims that users said it was unsafe. is this true or just for legal purposes?
